Abstract: By application of the system dynamics simulation model to evolution analysis, a probe is made into the various factors influencing the evolution of the industrial structure and the economic system structure of Yibin. By simulation of the development of different industries, efforts are made to find out the economic system structural adjustment optimization direction and thus to predict the approaches for the future industrial economic development in the region of Yibin. Some suggestions of realistic value are also presented for approaches concerning the regional economic development and industrial economic development of Yibin.
